Occurrence Details
At approximately 0900 Central Daylight Time on 04 August 2014, the ground controller at Winnipeg Richardson International Airport, Manitoba, cleared a DHC-8-402 aircraft, registration C-FOEN (serial number 4440), operating as WestJet Encore Ltd. flight WEN3112, to taxi for departure via Runway 31 and to hold short of Runway 36. The crew of WEN3112 acknowledged this clearance.
Shortly thereafter, the tower controller observed that WEN3112 had entered the Runway 36 protected area at the intersection with Runway 31 without a clearance to do so. As a result, the tower controller instructed a WestJet Boeing 737-700, operating as flight WJA318, which was on short final approach for Runway 36, to go around. The crew of WJA318 executed a go-around and subsequently landed without further incident.
The occurrence was investigated as a Class 3 investigation, which analyzes a small number of safety issues and may result in recommendations. No additional details regarding the aircraft occupants, injuries, or damage were reported in the source.
